I am using WCF for my project and i need to transit some entities through it.
The thing is that some of them have lists inside, with an enormeous ammount of items, and so forth, i cannot pass it through WCF, given its size.
How can I, through code, not load a given property from the database, but load all the rest?
By default the NH lists are lazy loaded - so unless you specified otherwise, the list will not be loaded.
However , the property will be an IProxy..something that won't be serializable. If you want you can probably set an [XmlIgnore] or [NotSerializable] (not sure how it's sent over wcf) on that specific property.
Having said that - do prefer using a DTO instead of sending your entity over the wire. See this for more about why you shouldn't send the entity.
Actually due to sirrocco I've endured myself. I a friend of mine helped me to finding this:
